NIDULARIACE2E 

 Oyathus (Bird's-nest Fungus). 



(1.) C. stercoreus, Detoni, Oheel, Report of the Botanic 

 Gardens, Sydney, 1911 (1912), 12. Syn. C. fimetarius, 

 Oooke, Handb. Aust. Fungi, No. 1213; Grant, Jiep. 6ot. 

 Gard. Sydney, 1901 (1902), 10; Oheel, Proc. Linn. Soc. 

 N.S.W., xxxii (1907), 204. 



Specimens of this species have been identified by Lloyd 

 (Nidulariacese, 1906, 20, and Letter No. 19, 1908), who 

 includes as synonyms C. Baileyi, Mass., Grev., Vol. 23, 

 (1892), 3, and in Bailey's Bot. Bull. No. viii (1893), 109. 

 We have also specimens in the National Herbarium, Sydney, 

 labelled C. plumbaginous, McAlp., which clearly belong to 

 this species. 



This species is very common on cow-dung and horse-dung 

 in meadow land and on manure in plantations throughout 

 the State, a very fine series of specimens being represented 

 in our collections and in the National Herbarium from the 

 following localities: — Sydney district, numerous collections 

 (Jan., Feb., March, June, August, Nov.); Hawkesbury River 

 (J. B. Cleland, Feb., 1911); Meryula, 25 miles east of Cobar 

 and Mount Boppy, near Cobar (L. Abrahams); Hill Top (E. 

 Oheel, May, 1913); Oobbity (J. H. Maiden, November, 1914); 

 Seaham (S. A. Hanscombe, July, 1915). 



The spores in Milson Island specimens, which were kindly 

 identified for us by Lloyd, were pear-shaped (35 x 20*5/*), 

 oval (26 x 22*5/*), or spherical (27 to 30/*) and in Penshurst 

 specimens oval (29 x 23/*). 



Some specimens from Barber's Creek, collected by J. H. 

 Maiden, and from Delegate, collected by W. Forsyth, 

 appear to belong to this species, but in both collections the 

 peridioles are absent.
